Provides advanced cryptographic solutions for securing cloud computing and confidential AI.

Cosmian, founded in Paris, specializes in securing cloud computing and confidential AI through advanced cryptographic solutions. The company has gained recognition for its proactive approach to post-quantum security, particularly with its Cosmian covercrypt solution, which achieved ETSI standardization in February 2025. This standardization underscores Cosmian's role in addressing the urgent need for quantum-resistant encryption, as highlighted by organizations like ANSSI and BSI.

Cosmian's product suite includes the Eviden KMS, a high-performance key management system compliant with FIPS 140-3, and Cosmian VM, a verifiable confidential virtual machine for secure cloud deployments. The company’s focus on hybrid cryptography ensures data protection against both classical and quantum threats. Cosmian’s solutions are designed for seamless integration into existing security frameworks, offering granular access control and efficient key management.

The company has also expanded its market presence through integrations with major cloud platforms like Azure, GCP, and AWS. Cosmian’s technical leadership includes cryptographer Chloé Hébant and Chief Scientific Officer David Pointcheval, who have been instrumental in advancing its cryptographic innovations. Despite its technological advancements, Cosmian faces challenges in scaling its offerings globally and addressing the complexities of post-quantum migration for enterprise clients.
